COMBINATION BAG TRANSFER AND FILLING MECHANISM Louis Hirschhorn' and Hans Ermscher, New. York,

N. Y., assignorsto Millie Patent; Holding (30.. Inc, New York, N. Y., a corporation or New 7 York Application June 18, 1932', Serial No. 617,955 n 11 Claims. (01'. 226-47) The present invention relates to devices. for forming and filling receptacles with desired substances and embodies, more specifically, an im-.

' proved mechanism for manipulating receptacles 5 which have been formed in a desired fashion in order that thereceptacles may be properly positioned and filled preparatory to being treated in any desired fashion.

- More particularly, the invention embodies an improveddevice for handling receptacles which have been formed of a porous or perforated structure inorder' that such receptacles may be directed from a device for supplying the receptacles continuously to a mechanism for properly positioning the receptacles for filling, such mechanism including means for filling the receptacles and directing th m to any mechanism for subsequently treating the same. I

The art of bagging substances, suchas tea, coffee, etc. now includes machines which form baglike receptacles from a continuous source of material, such machines severing the material and sewing the same into bags having'open ends. The prior art further includes transfer mechanism for directing the bag-like receptacles so formed to a filling mechanism, by means of which the receptacles are filled and directed to a device for closing the receptacles subsequent to the filling operation. In the last mentioned operations, viz; those taking placesubsequent to the sewing of the material into bag-like receptacles, the existing structures are of such nature as to place considerable strain upon the material from which the bag-like receptacles areformed. Such material must, therefore,'necessarily be of fairly good grade in order to withstand the rather severe treatment received durin the filling operations and such operations, in existing machines, are accompanied by considerable wastage due to the faulty operation of the elements of the filling and handling mechanism.

With a view to providing a bag or receptacle transfer and filling mechanism wherein the bags are handled'accurately and yet without undue strains imposed'thereon, the present invention has been designed and an object thereof is'to; provide a bag tran'sferand filling mechanism by means of which bags may be directed from a means ior supplying the same continuously to a positioning and filling mechanism, such means functioning positively and accurately and yet in p a manner such that excessive strain is not placed upon the material from ceptacle is formed.- A further object which the bag or reof the invention is to provide an improved 'tr-ansfer and filling mechanism. by means of which. a bag-like receptacle may be taken from a device for supplying receptacles continuously and placed upon. an. inverting. and filling mechanism in such fashion. that, through..- out the handling of the bag, positive stresses may be placed thereon uniformly along extended areas thereof, the unit stresses. sov imposed being within predetermined limits. I

Further objects, not specifically enumerated above, will be apparent as the invention is de.-. scribed-in greater detail in connection with the accompanying drawings, wherein: I

With reference to the above drawings and particularly to Figures 1, 2, and 3, the present invention will be seen to include a wheel 26 which is mounted upon a frame 2| and which carries a plurality of pairs of arms 22 over which lengths of material are mounted to be sewed into successive bag-like receptacles as illustrated in Figure 3. Inasmuch as the sewing operation constitutes no part of the present'invention a detailed description of the sewing mechanism is unnecessary herein.

Figures 4, 5, 6, 7, and 8 illustrate a mechanism for removing bags from the pairs of arms 22 in order that they may be directed to a mechanism to be described in detail hereinafter. As seen in Figure 4, a bagelike receptacle 23 is mounted upon the arms 22, the latter being of such construction as to separate the sides of the bag and tension the same to a desired extent as seen in Figure 5. The tensioning may be accomplished by means of a spring 24 to facilitate the engagement of the bag by a plurality of pairs of needles 25 and 26. Needles 25 are mounted upon a shaft 2? while needles 26 are secured to a shaft 28. Shafts 2'! and 28 are mounted upon a head 29 which is secured to guide rods 36 which are slidably mounted in a frame 3| (Figure 1) which is journaled in a bearing 32, formed upon the frame 2|.

Upon movement of the needles 25 and 26 into engagement with the bag .23, as shown in Figures 4 and 5, the tension placed upon the bag by the arms 22 is relieved by an arm 33 which engages an extension 34 formed upon one of the arms 22. Arm 33 is formed upon a lever 35 (Figure 2) which is pivoted at 36 to a stationary part of the frame 2| and is actuated by a cam 31, mounted upon a driving shaft 58 of the machine. Lever 35 is also provided with a link 39 which actuates a cutting mechanism 4|] to sever the stitches between successively sewed bags upon the wheel 20, as illustrated in Figure 3.

The movement of needles 25 and 26 with respect to' each other is controlled by a link 4| which is pivotally connected at 42 to an arm 43 which is secured to shaft 28. Segmental gears 44 are secured to the shafts 2'! and 28 and thus movement of link 4| in a given direction causes the pairs of needles 25 and 26 to be moved either toward each otheror to be separated. When the needles move into the bag 23, link 4| is so controlled that the needles are moved together ultimately to assume the position shown in Fig- Subsequent actuation of link 4H causes ure 5. the needles to be separated, as viewed in Figure '7, and the sides of the bag are spaced apart as illustrated in Figures '7 and 8.

Link 4| (Figure l) is connected to a bell crank lever 42 which is journaled upon an arm 3|, formed upon the frame 3|. Another arm 44 of the bell crank'lever 42 is connected through a universal connection 45 to a link 46 which is pivoted toan arml'l of a bell crank lever pivoted at 48. Another arm 49 of the bell crank lever is connected to a link 53 which is pivoted toan arm 5| at 52. Arm 5| is actuated by an arm 53 which is provided with a roller 54 adapted to engage the periphery of an operating cam 55. Rotation of the operating cam in the direction illustrated by the arrow inFigure' 1 may be effected by means of a gear 56 which is driven by a worm and worm wheel connection 51, driven by a main power shaft 58. The supporting structure for the foregoing elements preferably comprises a frame 59 which is integral with the frame 2|.

In order that the head 29 and guide rods 30 may be reciprocated upon the frame 3|, a link 66 is secured to one of the guide rods 30 and to an arm 6| of a lever pivoted at 62 upon the arm 43 of the frame 3|. Arm 6| is actuated by an arm 63 which is connected to a link through a universal connection 65. to an arm 66 upon which the pivoted connection 48 for the arms 4'! and 48 is made. The lower end of ,arm 65 is pivoted at 61 upon frame 59, the pivotal connection of 61 being concentric with the pivot 52 in order that arm 66 may be turned upon its pivot 61 without affecting the condition of the actuating mechanism for the needles 25 and 26, as above described. Pivotal movement of arm 66 is effected by means of a lever 68 (Figure 9), this lever being connected to a link 69 which is pivoted to a crank arm 10 at l I. Crank arm 10 is mounted upon the shaft upon which gear 56 is mounted and thus the reciprocation of head 29 and the actuation of needles 25 and 26 are synchronized. A spring 12 may be provided to urge the roller 54 against the periphery of cam in order that proper response may be had at all times to the motion of the cam.

As mentioned above, frame 3| is journaled at 32 in order that it may be properly actuate-d in accordance with the movement of head 29. The frame, accordingly, swings through an arc of 90", being in a substantially horizontal position when the needles are advanced into the bag as described in connection with Figures 4 and 5, and in a substantially vertical position when the bag, in the position illustrated in Figures 6, 7, and 8 is moved over the mechanism to be described presently for turning the bag inside out and filling the same. Such motion of the frame is effected by means of an actuating device, such as an arm 13 and the operation is effected without disturbing the operating mechanism for the head and needles by reason of the universal connections 45 and 65. 7

After the frame has been moved into a vertical position as shown in Figure 1, at which time the needles are in the position illustrated in Figures 6, '7, and 8 and a bag is mounted thereon, the frame 29 and guides 30 are lowered. This moves the bag over a properly positioned pair of fingers 14, as viewed in Figures 1, 10, and 11.

Fingers 14 are mounted upon a horizontal table l5 (Figuresl and 10) which is secured to a Link 64 is pivoted-.-

The pivoted fingers 7 4'. are each provided with av roller83.

which is adapted to engageuponthe periphery of a cam 84 which is secured to thespindle. 16. adjacent/the table .15. The "cam 84' is so formed as to move thev pivoted fingers 'I' l into the various positions shown in Figure 13, during the proper cycles of operation. 'For example, the upper left hand :pair offingers (as viewed in Figure; 13*) are shown as move-din close proximity in-order that the bag maybe drawn thereover to the position indicated in Figure. 11. When thefingers reach .a position under the filling mechanism describedhereinafter, the cam causes. the pivoted finger of the correspondingpair of fingers to move away from the stationary finger as indicated in the lower right hand portion of Figure, I3. Such motionisaccomplished by means of a spring ilfi-and a guide rod-86..

After the bags have been placed over the'supporting fingerathe head 29 and needles 215. and 2% are, elevated in order'tha't: the bags may rest freely upon the supportingfingers. To prevent the'bags from following. the needles upwardly,

presser feet 8 1 and 88 are. provided, engaging the sides of: the bags 23 as. illustrated in Figures 10 I and ll. Presser foot 81 is mounted upon a pair of rods 89 having. limiting heads. 90 which are slidably supported in an arm M which is pivoted at '92 .to a stationary portion. :of the machine. Presser foot 88 is mounted upon .a plurality of rods- 93 which are slidably mounted in an arm 3%, pivoted at 95 upon a stationary portion of the machine and actuated by a reciprocable. link 98 which is pivotally connected to the end of arm 94. Springs!" normally urge the presser feet 8'! and 88 outwardly into engagement with the.

sides of bags 23 and the movement of arms 9! and 94 is synchronized by means of a link 98 which is pivotally connected between the arms;

Link 96 is pivoted to the end of an arm 99 which is secured to a sleeve Hi8, formed upon a bracket Ilii which is pivoted at N32 to the frame of the machine. Bracket IIlI is formed with an arm I93 which is provided with a roller I04 upon the end thereof, this roller being adapted to engage the periphery of a cam I85, being urged thereagainst by means of a spring I96. Mounted to rotate with cam I 85 are gear segments ID'I which are adapted to engage a mutilated gear I08 mounted upon a shaft W9. Locking cam segments I I0 rotate with gear segments I8! and are adapted to engage a cooperating cam segment I I I which rotates with the multilated gear I08. In this fashion, shaft ms ie-intermittently -rdtated and thus rotates,f-in

After the bags have b'een placed over the supporting fingers I4 as illustrated in Figure 1-1,

th'etable' 'lfi i's'roltated to bring the bag and sup- "porting fingers under a reciprocating spout 'FHI.

The position of the 'fin'gers' 'and bag under the spout is shown in Figure 15 and after the fingers are properly positioned beneathfth'e spout the spout d'escends, drawin gthe upper po'rtion'of the 4 bag downwardly between the supporting 'fi'ngeis to turn the bag inside out and simultaneously fill the samewith'a desired quantity of substance. After the bag has been inverted and filled it is received upon a table "I I5 from which it maybe removed in any desired fashion.

It will thus be seen that a mechanism has been provided which operates positively andeffectively to transferbags from a bag supplying member to are impressed upon the fabric of the bags and a very cheap material may thus be used in making the same.' The effective manner in which. the i bags are manipulated insures accurate functioning of the machine with no faulty operations.
